How it is calculated

Total A and total B = sum of items for each option.

Monthly difference = |A − B|; yearly = monthly × 12. Each item shows B − A.

  • Monthly costs for each option: 6 example rows

Result: Option B saves per year — $1,320.00 (option a monthly total: $1,010.00; option b monthly total: $900.00; monthly difference: $110.00).

Money-saving tips
